Ellis Simms and Tatsuhiro Sakamoto added further goals in the second period to complete a comprehensive victory.
"It's a period where we're playing well. All the work that we do is coming together. It won't always be that way, but at this point, we're very clinical in front of goal," said former England midfielder Lampard.
"We're creating a lot of chances and four clean sheets is obviously great for us because the early games, we were conceding a lot."
